In Criterion 14, GRIHA Version 03, when the building is simulated with a glazing of SHGC - 0.45 in Resbuild India, the percentage savings decrease from 41% to 38% because the base case SHGC is 0.25.

Query

In Criterion 14, GRIHA Version 03, when the building is simulated with a glazing of SHGC - 0.45 in Resbuild India, the percentage savings decrease from 41% to 38% because the base case SHGC is 0.25.

Solution

Percentage reduction shown in toolkit is for a reference building which software automatically assumes based on type of building and climate. However, this saving is not GRIHA saving since benchmark EPI for GRIHA is different, and hence it is required to manually calculate the saving for GRIHA after taking the energy consumption value from the Resbuild Tool.
